MOLD.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed May 22, 1905. $e1'ia1No. 261,594.

To (ZZZ whom it may concern:

Be it known that I, JOHN A. STRANsKY, a citizen of the United States,residing at Pukwana, in the county of Brule and State of South Dakota,have invented new and useful Improvements in Molds, of which thefollowing is a specification.

My invention relates to certain new and useful improvements in molds,and has for its object to provide a mold of novel construction which inoperation will be adapted to receive various kinds of partitionsextending either transversely or longitudinally, or both transverselyand longitudinally, of the mold, whereby various classes of articles maybe cast in the same mold and a plurality of each article may be moldedat the same time.

In order that the invention may be under stood, I have illustrated thesame in the accompanying drawings, in which Figure 1 is a perspectiveview of the mold proper, illustrating the means for disengaging at oneoperation the sides and ends of the mold to permit them to drop. Fig. 2is a transverse sectional View. Fig. 3 is a longitudinal section. Fig. 4is a top plan view of the mold, showing partitions arranged therein in amanner to adapt the mold to the molding of concrete posts. Figs. 5, 6,and 7 are also plan views, Fig. 5 showing the arrangementof thepartitions for molding cement pavingtiles, Fig. 6 the arrangement of thepartitions for molding cement building-blocks, and Fig. 7 showing thearrangement of the partitions for molding cement bricks.

The numerals 1 2 indicate the sides, and 3 4 the ends, of the mold,which are pivotally connected to the bottom 5 by means of hinges 6, thearrangement being such that when the ends are released, as hereinafterdescribed, said ends and the sides may fall down and permit the contentsof the mold to be removed. Cleats are secured to the inner side of eachof the ends 3 4 at their outer extremities, said cleats engaging thesides 1 2 of the mold and holding them in an upright position.

8 indicates spring-catches, two of which are secured at one end on thetop of each of the sides 1 2 toward the outer end thereof, as indicatedat 9, said spring-catches engaging over the ends 3 4 and serving toretain them in an upright position.

10 indicates bars which are inserted in loops 11 in the spring-catches 8at each end of the mold, secured to which bars are chains 12, which areconnected with a central chain 13, which passes over a pulley 14,mounted, say, in the ceiling of the room where the mold is located, andby pulling on which chain 13 the bars 10 will be caused to raise theouter ends of the spring-catches 8, which operation will permit the ends3 and 4 to fall and the sides 1 and 2 also as soon as the chain isreleased.

Referring to Fig. 4, 15 indicates a series of partitions which arearranged to extend longitudinally of the mold from end to end thereof,said partitions being caused to converge toward one end of the mold togive a tapering shape to the posts by means of tapering pallets or falsebottoms 16, inserted between the partitions 15. WVedges 17 are insertedbetween the outermost partitions 15 and the sides of the mold. As shownin the drawings, five partitions are arranged in the mold, and hencesaid mold is adapted to have four posts molded at one time. After thematerial poured between the partitions to form the posts has hardenedthe chain 13 is operated to release the ends of the mold and permit thesides and ends to fall, as above described, and the pallets 16 may thenbe withdrawn, removing the posts from between the partitions and out ofthe mold.

In Fig. 5 I employ only transverse partitions 18, extending from side toside of the mold, and, as shown, rectangular blocks of cement suitablefor paving-tiles may be molded by pouring material between the saidpartitions. After the material has hardened the sides and ends aredropped and the tiles removed one at a time from the mold, or ifpreferred, in this and the subsequent operations, to be described, afalse bottom can be employed in the mold, so that all the blocks,bricks, or other objects molded can be removed at one time.

In Figs. 6 and 7 transverse and longitudinal partitions 19 and 20 areboth employed, and according to the number of these and the distance atwhich they are spaced apart I can mold blocks of a size suitable forbuilding purposes, as shown in Fig. 6, or for bricks, as shown in Fig.7.

It will readily be seen that other dispositions of partitions may bemade in the mold than those described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. A mold comprisinga bottomhaving sides and ends hinged thereto, means carried by the sides andends for holding said sides and ends in an upright position, and meansfor simultaneously releasing said sides and ends.

2. A mold comprising a bottom having sides and ends hinged thereto,means carried by the ends for engaging the sides to hold them in anupright position, means carried by the sides for engaging the ends tohold them in an upright position, and means for simultaneously releasingthe engagement with both of the ends.

3. Amold com prisingabottom having sides and ends hinged thereto, meanscarried by the ends for engaging the sides to hold them in an uprightposition, spring-catches carried by the sides for engaging the ends tohold the latter in an upright position, bars removably engaging thespring-catches at each end of the mold, a pulley supported above saidmold,

and a chain operably connected With said rods and passed over saidpulley.

4:. In combination With a mold having hinged side and end members, aseries of longitudinal partitions removably mounted therein andextending from end to end of the mold, a tapering pallet insertedbetween each two partitions and extending from end to end thereof, and aWedge inserted between each outermost partition and the side of the moldand also extending from end to end thereof, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

JOHN A. STRANSKY.
